Drafted in the 1st round (8th overall) by the San Diego Padres in 2016 (signed for $3,963,045)

Quantrill's father Paul pitched in the majors for parts of 14 seasons and is Canada's all-time leader in games pitched. Quantrill grew up around big league clubhouses and starring for Canadian national teams before arriving at Stanford, after turning down the Yankees as a 26th-round pick in 2013. He made his reputation as a collegian instantly, becoming the first Cardinal freshman to start Opening Day since Mike Mussina in 1988 and leading the team to a regional victory at Indiana. He pitched in relief on one day's rest in the regional, beating Kyle Schwarber, Sam Travis and the Hoosiers, and was the Coastal Plain League's No. 1 prospect that summer, including a start where he flashed premium stuff against USA Baseball's Collegiate National Team. However, Quantrill has made just three starts since then, all of them in 2015. He had Tommy John surgery March 20 that year and hasn't pitched in a game since. Stanford and his family have remained mum on his return. When healthy, Quantrill pitches off an 89-94 mph fastball with sinking life and a plus changeup with similar life and action. He has thrown both a slider and curveball in the past, flashing average with a slider in the 78-80 mph range. If Quantrill doesn't return to the mound for the Cardinal, he'll likely throw bullpens or simulated games just before the draft, presenting a true wild card for June.
